[Asterisk-Users] Understanding the "Hint" priority.

[Ryan Courtnage]

Hi all,

I'm trying to get a better understanding of the 'Hint' priority for use
with Snom phones, etc. 

>From the Wiki, I understand that the following will work:

  exten => 200,hint,sip/200
  exten => 200,1,Dial(sip/200)
  exten => 201,hint,sip/300
  exten => 201,1,Dial(sip/201)

When exactly is 'Hint' executed?  After someone dials '200' or '201'?
Or does the 'hint' priority apply it's magic at dialplan load time?

Suppose I want to dial multiple extensions at once:

exten => 999,1,Dial(sip/200&sip/201)

.. can hint work in this case?  If so, would I simply pass multiple
channels to hint? ie:

exten => 999,hint,sip/200&sip/201
exten => 999,1,Dial(sip/200&sip/201)

?

Thanks in advance,
Confused
